The principal object of my invention is to provide a machine, preferably automatic, for inserting bristles into ferrules preparatory to making complete brushes.

A feature of my invention is mechanism for inserting bristles into ferrules and this with great speed and with great accuracy.

Another feature is a secondary member for feeding the supply of bristles.

10`l Another feature is a tapper for evening upy the ends of the bristles.

Numerous other features will be pointed out below.

On a suitable bed I is Vmounted an upright 45,. frame 2 supporting horizontal shaft 3 on which are mounted various parts referred to below.' L ASupported on bed I is raceway 4 between members 5 and 6 to receive a large quantity of bristles I extending transversely nof Vthe machine, the member IV being a support. Weight 8, acting through cord 9 and carriageY YIII and beat-up member II, tends to advance the bristles in the racewayk against stop I2, the latter being reciprocated through member 5 by link I3 and lever .I4,the latter beingpivotedrat I5 and its end I5 carrying a roller I'I which rides on cam I8 mounted on main drive shaft I8 which is driven by belt 28 from any suitable source of power. Cooperating with stop I2 in order to separate the desired bunch of bristles is member 2I which is 5f xed to slide 22 sliding in ways 23 in the main frame 2 of the machine. This slide is operated through yckemernber 24 having mounted thereon roll 25 reciprocated vertically by the cam 25 mounted on shaft 3, which is driven from the 10' v main shaft I 9 by chain 21.

The feed lever 28 feeds the bristles against stop I2, being pivoted at 29 to lever 38 which is pivoted at 3i the lever 38 being actuated by cam 32 thus imparting a vertical movement to lever 15 34. Horizontal movement of lever 28 is imparted by projection 33 of lever 28 coming in contact with cam 34.

A secondary feed lever 35 is pivoted at 35 to lever 3l which in turn is pivoted at 38, lever 3l' 26 being actuated through cam roll 39 and cam 45, the latter being mounted on shaft 4I in brackets 42 fast to the frameZ. The shaft 4i is driven by chain 48 from the shaft 3. i

Feed lever 35 is connected by link 50 to bell 25TY crank 5I, pivoted to the frame 2. Spring 52, through bell crank 5I and link 55, tends to put tension on lever 35, stopy 53 limiting movement of bell crank 5I when Ylever 35 is withdrawn from the bristles. 30

Tapper 44 evens up one set of ends of the bristles between members I2 and 2I and is reciprocated against said ends through lever 45, to

Vwhich it is fixed, lever 45 being pivoted at 45 to bracket 41 xed to frame 2. Lever 45 is recipro- 35 cated by link 48 which itself is reciprocated by lever 48 described below.

The picking members 54 and 55 pivoted at 55 are mounted on ear 5l which is part of slide member 58 sliding in guideways 59 in the casting 58 40 on the bed I. Said jaws have extensions 5I and 62 connected by links 63 and 64 to a pivotV 65 which is connected to rod 66. Pivot 65 has mounted thereon a roll 81. Slide 58 is actuated through link 58 and lever 69, pivoted at 10, by 45 cam 1I. The action of the cam 'II moves slide VElite the right so that the pickers 54 and 55- register with the bunch of bristles to be picked off. The extreme movement of slide 58 snaps the toggle formed by links 53 and 54 to the left by 50 means of the stop 'I2 on rod 66 coming in contact with the abutment 13. This movement closes the picking members 54 and 55 over the bunch` of bristles to be picked off. The slide 58 is then returned to the position of Figure 1 by cam. 1I. 55`l` Roll 61 passes through slot 14 in the upstanding member of slide 58. When the transfer jaws, to be described below, take hold of the bristles the picking members 54 and 55 are opened by means of the bell crank 15 pivoted at 16 coming in contact with the roll 61 and snapping the toggle to the right. The bell crank 15 is actuated by the push-up rod 16a sliding in guide 11 pushed up by lever 18 pivoted at 19 having mounted thereon a roll actuated by cam 8| on main shaft I9.

It will be readily understood that by the rotation of cam 8| the lever 18 is raised lifting the push rod 16 against the arm of bell crank 15 moving the upstanding arm of bell crank 15 to the right so as to come in contact with roller 61 thereby breaking the toggle to the right. A spring 82 held by ears 83 tends to draw the picker members together and consequently exert tension on theY toggle. A stop 84 is mounted on the member 62 to limit the closing movement of the picker members.

Jaws and 86 transfer the bunch of bristles from the picker members to the position shown in Figure 2. These jaws 85 and 86 are mounted on stud 81 by means of U-shaped brackets 88 and 89. The stud 81 is mounted in side members 90 and 9| which in turn are fastened to a U-shaped member 92 fast to the gear 93, which is mounted in a slide 94 sliding in ways 95 fast to the base 96 by screws 91. The rearward extension 94EL of the slide 94 has mounted thereon a lever 98 pivoted at 99Y and is actuated by means of the member |00 having mounted on its top side a roll |0| actuated by cam |02 mounted on vertical shaft |03. Said member |00 has mounted on its lower side Vcam roll |04 actuated by cam |05 mounted on said shaft |03. Shaft |03 has fast to it bevel gear |06 meshing with bevel gear |01 iixed to one end of horizontal shaft |08 mounted in bearings |09 and |I0, the other end of shaft |08 having fixed to it bevel gear I I I meshing with bevel gear ||2 fixed to shaft ||3 mounted in bearings I4 and I I5. The shaft I I3 is driven frommain shaft I9 by chain I6. Y Gear 93 is in mesh with rack I I1 mounted on bracket I I8 fast to bed of the machine, clip ||9 being provided.

When the slide 94 moves toward the front of the machine the gear 93 meshing with rack I|1 turns the open jaws 85 and 86 through 90 to a position to grasp the bunch of bristles held by the picking members. The closing of the jaws 85 and 86 to grasp the bunch of bristles is effected by means of the lever 49 pivoted at |20 having mounted thereon a roll |2| actuated by cam |22 mounted on shaft 3. The spring |22a tends to keep the roll |2| against the cam |22. The rearward ends of the jaws 85 and 86 are provided withtoggles |23 and |24 pivoted at |25, upon which are mounted rolls |26 and |26B- sliding in slots |21 formed in the members 90 and 9|. By breaking the toggles |23 and |24 by means of lever 49 coming in contact with the roll |25 snapping the toggle to the left into thel position shown in Figure 4 the jaws 85 and 86 are closed about the bunch of bristles as shown in Figure 4. When the transfer jaws 85 and 86 have closed on the bunch of bristles the slide 94 is retracted and the jaws rotated to the position of Figure 2 by means of link 98 and the associated mechanism.

Mounted on the slide |28 are two pusher fingers |29 and |30 described below. The slide |28 is reciprocated by means of link I3 I, lever |32 pivoted at |33 and connected at |34 to fork lever |35 having thereon roll |36 actuated by cam |31 fastenedto main shaft I9.

sndabiy mounted n, slide,

|28 is the rod |38 fast to another slide I 39 as best? shown in Figure 8. Two stop collars |40 and |4|4 fast to rod |38 permit lost motion to take place when the slide |28 is reciprocated. When the slide |28 is moved to the right in Figure 8 it picks 5 up the stop collar |40 and through it moves the slide |39, which has pivoted at |42 and |43 the ferrule-carrying jaws |44 and |45. As the slide |28 carrying the pusher fingers |29 and |30 is moved to the right the pusher ngers pick up the 10 bottom ferrule |45 from the magazine |41 and present it to the ferrule-carrying jaws as shown in dotted lines in Figure 1l. Further movement of slide |28 moves the slide |39 and jaws |44 and |45 to the right in Figure 8 surrounding the 15 bunch of bristles then held in jaws 85 and 86, the tapered faces |44a and |45a pressing the ends of the bristles together so that they are guided part way through the ferrule as shown in Figure 15. The bunch of bristles, after being pressed to- 20 gether, as Vabove described, separate naturally enough to ll the ferrule and frictionally engage its inner wall; As this is taking place jaws |48 and |49 close around the bunch of bristles. Further movement of slide |28 to the right presents 25A the rolls |50 and I5I, mounted on the ferrule carrying jaws |44 and |45, against the wedgeshaped member xedly mounted on a. bracket as shown in Figure 2. It will be clear that as the rolls 44a and 45a come inY contact with the bev- 30 elled faces of wedge |52 the jaws |44 and |45 will open sufficiently to allow the ferrule to remain in said engagement with the bristles whose ends are held by jaws 85 and 86, the jaws |44 and |45 returning to their original position. When the fer- 35 rule |46 is presented to the ferrule-carrying jaws |44 and |45 it is brought in engagement with the recesses |53 and |54 as shown in Figure l1 and is so located that the opening between the jaws |44 and |45 at the inner ends of faces |44a and 4Q IlfL is slightly less than the adjacent open end of the ferrule so that the ends of the bristles will be sure to be inserted in the ferrule. Ferrulecarrying jaws |44 and |45 are pressed together by spring |55. Stud |56 is mounted on slide |51 45 sliding in ways |58 and connected by spring |59 to member |60 fast to slide |28. The end of the stud |56 fits into the recesses |6I and |62 of jaws |44 and |45 shown in Figure II.

As the jaws |44 and |45 move to the right and 50 are opened by wedge Y|52 the end of the stud |56 is pressed back by the spring |59 into. the

lrecesses |63 and |64 holding jaws |44 and |45 open during the retraction so that the jaws are free of the ferrule until the small end of stud 55 |56 comes in contact with the end |65 of guideway |58. Further movement of jaws |44 and |45 to the left brings the large end of the stud |56 back to position within recesses ISI and |62.

The pusher fingers |29 and |30 are held in slots 60 |65 and |66 in slide |28 by clamping bars |61.

The magazineV |41 is held in place on the bed by adjustable brackets |68 and |69 and has an opening |18 to Vallow the bottom ferrule to be pushed to the right in Figure 8 between jaws |44 65 and |45 by pusher fingers |29 and |30, extension |1| supporting the lower jaw |45 until wedge I 52 acts to open the jaws.

The transfer jaws 85 and 86 are opened by means of the lever |12 pivoted at |13 having 70 a cam roll |14 actuated by cam |15 at the desired time, lever |12 coming in contact with roller |26a mounted on the pivot |25 snapping the toggle |23 and |24 to the right opening the jaws into the position .shown in Figure 5,'spring |16 surround- 75 ing stud |11 fast to the jaw 86,V said stud |11 passing through an opening in jaw 85. Said spring puts tension between jaws 85 and 86 by its abutment against said jaws.

The holding jaws |48 and his are connected to links H8 and |19 pivoted at |80 on the member- |8| fast to the bed`of the machine. The pivot |82 of the jaws |58 and M9 has mounted thereon rolls |83 and |84 sliding in slots such as |83a and actuated by cams E88 shown in Figures 13 and 14. Said cams |85 are fixed to shaft |88. It will be clear that as cams |86 rotate as indicated by the arrow in Figure 13 coming in contact with rolls |88 and |84 holding jaws |48 and |49 are closed as shown in Figure 14. To return the jaws` |48 and |49 to the open position the levers |87, pivoted at |88 to members 89 and connected to the pivot |82 and having spring |88 connected to member IB! on the member |8| are drawn back opening jaws m8 and |49 to their wide open position. It will be clear that the jaws |48 and M8, as in the case ofthe other jaws previously described, when closed are side by side and .are formed to constitute, when closed, an opening of approximately the size and shape of the ferrule into which the bristles are to be inserted.

In using my machine any desired quantity of bristles are placed in the raceway, lying horizontally, and are pressed forward by member and feeding member 28 and secondary feeding -member 35 against stop I2, member 2| separating a number of the bristles to form the desired bunch. Members 28 and 35 act alternately to feed the bristles forward, this alternate action ensuring continuous feeding because either one or the other of said feeding members .will always be in action. The tapper acts to even up the ends n of the bristles at the lforward end of the raceway. TheV bunch of bristles separated from the rest of the bristles by the stop l2 and member 2| are then picked oif by jaws 54 and 55 engaging the exposed ends of the bristles, the stop I2 moving up immediately to engage the bristles to the rear ofthe picker members as the latter move to the left, these jaws being then brought back to their position in Figure 2 where they are held until the transfer jaws 85 and 86 are rotated 90 into position to receive the bunch of bristles from the picking members. The transfer jaws then grip the bunch and the picking members are opened and the transfer jaws are rotated with the bunch of bristles to the position of Figure 2. A ferrule having been removed from the magazine and placed in the ferrule-carrying jaws, the latter are advanced toward the bristles. Before the ferrulecarrying jaws reach the bristles jaws |48 and M8 close temporarily to bring the bunch of bristles closer together preparatory to insertion between the ferrule-carrying jaws and remain closed until the ends of the bunch enter between the jaws |84 and |45. As the jaws Idil and |45 are moved to the right the ferrule surrounds the bunch of bristles, jaws |48 and |49 having opened immediately after engagement of the ends of the bunch with the jaws Mil and E45 to permit passage of jaws Mld and |55. When the ferrule has been advanced to the desired position surrounding the bunch of ferrule-carrying jaws are opened and then withdrawn leaving the ferrule and bristles held by jaws 85 and 86. Jaws 85 and 86 are Y then opened allowing the ferrule V.and bristlesV to, drop onto the bed of the machine, although of course a suitable chute might be provided. It will be understood that the number of bristles in the bunch is suicient to ll the ferrule compactly so l.
